RGB mute commands
RGB mute X3 *1B Vmt X3 *1 Mute output X3 video (RGB off).
RGB unmute X3 *0B Vmt X3 *0 Unmute output X3 video (RGB on).
Read RGB mute X3 B X8 1= mute on, 0 = mute off.
Global RGB mute 1*B Vmt1 Mute all video outputs.
Global RGB unmute 0*B Vmt0 Unmute all video outputs.
An IR 501 user can mute video and/or audio with a string of IR commands that cannot be
duplicated by a computer or control system sending SIS commands. The switcher sends the
following responses:
IR 501 video and audio mute {none} Mut X3 *1 Output X3 ’s video and audio are
muted.
IR 501 video mute {none} Vmt X3 *1 Output X3 ’s video is muted.
IR 501 video and audio unmute {none} Zpz Output X3 ’s video and audio are
unmuted.
Audio input gain and attenuation
Set audio input gain to +dB value X1 * X5 G In X1 •Aud X4
Example: 1*2G In1•Aud+02 Set input 1 audio gain to +2 dB.
Set audio input attenuation to -dB value X1 * X6 g In X1 •Aud X4
Increment gain up X1 +G In X1 •Aud X4
Example: 5+G In5•Aud+03 Audio input 5 level incremented
from +2 dB to +3 dB.
Decrement gain down X1 -G In X1 •Aud X4
Example: 7-G In7•Aud-09 Audio input 7 level decremented
from -8 dB to -9 dB.
Read input gain X1 G X4
Example: 3G -06 Audio input 3 level is -6 dB.
Audio output level
Set audio output to consumer level X3 *0*40# Out X3 •Lvl0 Set output X3 level to the
(–10 dBV) consumer (–10 dBV) level.
Set audio output level to pro level X3 *1*40# Out X3 •Lvl1 Set output X3 level to the pro
(+4 Dbu) (+4 dBu) level (the default level).
Read output level X3 *40# X9
Example: 3*40# 1 Output 3 audio level is pro
(+4 dBu) level .
Audio mute commands
Audio mute X3 *1Z Amt X3 *1 Mute output X3 audio (audio off).
Audio unmute X3 *0Z Amt X3 *0 Unmute output X3 audio
(audio on).
Read audio mute X3 Z X8 1= mute on, 0 = mute off.
Global audio mute 1*Z Amt1 Mute all audio outputs.
Global audio unmute 0*Z Amt0 Unmute all audio outputs.
